Jethro_uk laid this down on his screen :
So why the need for new gas pipes to all the flats? Or are they in fact
not gas but water? A layman might well not know the difference.

Sadly, running any new services through a fire protected area might well
compromise that, if badly done.

Whoa !!!!!

Wasn't gas for high rises banned after Ronan Point ????? !!!!!!

I thought, only for flats where the walls form an intgral part of the
structure, where if there were an explosion - it could blow a wall
panel out causing a collapse.
